Tiny atoms
This is the smallest unit of matter that still keeps the properties of an element.
What is an atom?
These circular paths around the nucleus where electrons move are called this.
What are electron shells?
This is formed when two or more atoms join together.
What is a molecule?
What does AMU stand for?
What is Atomic Mass Unit?
A pure substance made of only one type of atom.
What is an element?
These two tiny particles are found inside the nucleus of an atom.
What are protons and neutrons?
The scientist who created the Bohr model of the atom.
Who is Niels Bohr?
The type of bond where atoms share electrons.
What is a chemical bond?
The total number of protons and neutrons in an atom.
What is the mass number?
Where can you find all known elements organized?
What is the periodic table?
This negatively charged particle orbits around the nucleus of an atom.
What is an electron?
In a Bohr model, this part of the atom is located in the center.
What is the nucleus?
Give an example of a simple compound and its chemical formula.
Example: Water (H₂O)
How to calculate the mass of an atom using AMU.
Add the number of protons and neutrons to find the total weight. (and kinda the electrons)
Name three elements you might find in the human body.
Carbon, Oxygen, Hydrogen
Name the three main parts of an atom.
What are protons, neutrons, and electrons?
Explain how electrons are arranged in a Bohr model.
Electrons are arranged in circular shells around the nucleus, with each shell having a specific energy level.
Explain how ionic and covalent compounds are different.
Ionic compounds transfer electrons, while covalent compounds share electrons.
Explain how the number of protons determines an element's identity.
The number of protons defines the element's atomic number and identity.
Explain how elements are different from compounds.
Elements are single types of atoms, while compounds are combinations of different atoms.
Explain how atoms of different elements are different from each other.
Atoms differ in the number of protons, which determines the element and its unique properties.
Describe how the number of electron shells relates to an atom's properties.
More electron shells typically mean the atom is larger and has more complex chemical behavior.
Describe the process of how atoms combine to form compounds.
Atoms combine by sharing electrons to create a chemical bond.
Describe how isotopes differ from each other.
Isotopes have the same number of protons but different numbers of neutrons.
Describe how elements are classified on the periodic table.
Elements are classified by their atomic number/the number of protons in their nucleus.
